Abstract

<p> On a heavy traffic route where infrastructure maintenance is important, the Hosen Viaduct, located at the railroad intersection of Yokohama Shindo, has been in service for 48 years since 1971. The reinforced concrete slabs have deteriorated and damaged due to aging and traffic loads, and it was necessary to repair them immediately to ensure their load-bearing capacity. The repair of slabs is generally performed by partial or full-layer replacement of the damaged part. However, as a measure to prolong the service life of the slabs until drastic measures are taken, a partial replacement of the slab concrete with J-THIFCOM was performed on the top surface of the slabs, and the effect of the repair was subsequently verified</p>
